RELATED APPLICATIONS

The entire disclosure of U.S. Provisional Patent Application Ser. No. 61/224,043, filed Jul. 8, 2009, titled CONTAINER FOR SEGREGATING AND BLENDING MULTIPLE SEED TYPES, is expressly incorporated by reference herein.

FIELD

The present invention relates to methods and apparatus for blending multiple components of a mixture and in particular to the blending of multiple seeds in a seed mixture.

BACKGROUND

GMO (“genetically modified organism”) seeds have been developed which produce plants that are resistant to at least one of a particular type or family of pests or pesticides such as insects, fungi, insecticides, and herbicides. GMO seeds are often planted as part of a mixture including refuge seed. The refuge seed has not been genetically modified in the same way as the GMO seed and does not produce a resistant plant.

In some situations, the mixture of GMO seed and refuge seed is planted in an effort to prevent the insect population from becoming resistant to a particular type of plant produced by the GMO seed. Regulatory bodies such as the EPA help determine and regulate the ratio of refuge seed to GMO seed that must be planted to preserve the usefulness of the GMO seed. Growers may plant refuge seed separately from GMO seed or acquire premixed GMO and refuge seed from seed suppliers.

DETAILED DESCRIPTION OF THE DRAWINGS

The embodiments disclosed below are not intended to be exhaustive or to limit the invention to the precise forms disclosed in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in the art may utilize their teachings. While the present disclosure is primarily directed to the blending of seeds which are stored in multiple compartments of a container, it should be understood that the features disclosed herein may have application to the blending of other components stored in multiple compartments of a container.

Referring to FIG. 1, a container 100 is shown. Container 100 includes a front upstanding wall 102, a rear upstanding wall 104, a first side upstanding wall 106 and a second side upstanding wall 108. Walls 102-108 cooperate to define an interior 110 of container 100. Although container 100 is shown as being a four sided container, container 100 may have any number of sides, be generally cylindrical, be generally elliptical, or any other suitable shape. In one embodiment, container 100 is made of polyethylene. In one embodiment, container 100 is a collapsible container, such as the Center Flow Bulk Container available from Buckhorn located at 55 West TechneCenter Drive in Milford, Ohio 45150.

Referring to FIGS. 2 and 4, container 100 also includes walls 112, 114, 116, and 118 which are angled inward from an upper portion 120 of container 100 to a lower portion 122 of container 100. Referring to FIGS. 9 and 10, in the illustrated embodiment, walls 112-118 are angled inward along their whole extend. In one embodiment, walls 112-118 are angled inward only for a portion proximate to lower portion 122 and generally straight for the remainder of walls 112-114. In one embodiment, walls 112-118 intersect with walls 102-108 not at upper portion 120, but rather in a middle portion of walls 102-108. In either of these two cases the volume of interior 110 is increased. The angling of walls 112-118 assist in directing the seed in interior 110 towards an opening 140 (see FIG. 5) of container 100 in a bottom wall 124.

Referring to FIG. 5, a bottom wall 124 of container 100 is shown. Bottom wall 124 supports a gate 130 which is moveably coupled to bottom wall 124. In the illustrated embodiment, gate 130 is slideably coupled to bottom wall 124 to permit gate 130 to move in direction 132 and direction 134. An operator may grasp a handle 138 to aid in moving gate 130 in direction 132 and direction 134.

Referring to FIG. 10, in one embodiment, container 100 includes channel members 136 which support gate 130 and permit the movement of gate 130 in directions 132 and 134. Channel members 136, in one embodiment, are coupled to bottom wall 124. Channel members 136, in one embodiment, are integrally formed as part of bottom wall 124.

Returning to FIG. 5, an opening 140 is formed in bottom wall 124. Material, such as seeds, being held in interior 110 passes through opening 140 when gate 130 is moved in direction 132. Opening 140 is bounded by lower edges 142-148 of walls 112-118, respectively.

Returning to FIG. 1, interior 110 is divided into a first compartment 150 and a second compartment 152. Second compartment 152 is separate from first compartment 150, such that seeds stored in first compartment 150 remain segregated from seeds stored in second compartment 152 while being stored in container 100.

Second compartment 152 is formed by a container 160. In the illustrated embodiment, container 160 is formed of walls 162-168. Each of walls 162-168 are shown as angling inward from upper portion 120 to lower portion 122. The angling of walls 162-168 assist in directing the seed in second compartment 152 towards an opening 170 (see FIG. 5) of container 100 in a bottom wall 124. Material, such as seeds, being held in interior 110 passes through opening 170 when gate 130 is moved in direction 132. Opening 170 is bounded by lower edges 172-178 of walls 162-168, respectively. In one embodiment, lower edges 172-178 are generally coplanar with lower edges 142-148.

Container 160, in the illustrated embodiment, is spaced apart from walls 112-118 at upper portion 120 of container 100. The upper portion 180 of container 160 is generally secured in place with support bars 182-188. In one embodiment, support bars 182-188 are releasably coupled to one of interior 110 and container 160 to allow the removal of container 160 from interior 110 of container 100 or the positioning of container 160 in interior 110 of container 100 prior to seed being introduced into interior 110 of container 100. In an alternative embodiment, container 160 rests against at least one of walls 112-118. Although container 160 is shown as being removable relative to container 100, in one embodiment, container 160 is rigidly coupled to container 100 or integrally formed as part of interior 110.

Referring to FIG. 1, container 160 includes a lid 190 which may be secured to upper portion 180 of container 160. Lid 190 includes cutouts 192 which receive supports 182-188. In one embodiment, lid 190 is a tamper proof lid which may be locked relative to container 160 to limit access to second compartment 152. In one embodiment, lid 190 is color-coded to indicate the type of seed being carried in second compartment 152. In one embodiment, lid 190 is made of a material which allows visual inspection of the contents of second compartment 152 from an exterior of container 160.

Referring to FIG. 3, supports 200 are coupled to wall 112 and wall 114. Supports 200 define channels 202 which receive and locate the end of container 160 corresponding to opening 170. As shown in FIG. 5, supports 200 locate container 160 such that lower edge 172 generally coincides with lower edge 142 and lower edge 174 generally coincides with lower edge 144. This is illustrated in FIG. 9, wherein opening 170 of second compartment 152 is shown to be generally coextensive with opening 140 of first compartment 150. In contrast, along the orthogonal direction, as shown in FIG. 10, opening 170 of second compartment 152 is not coextensive with opening 140 of first compartment 150.

Returning to FIG. 5, as discussed above, the lengths of opening 140 and opening 170 are generally the same and the widths of opening 140 and opening 170 differ. By having the lengths the same, a ratio of the area of opening 170 to the area of opening 140 exposed by gate 130 when gate 130 is moved in direction 132 remains generally constant independent of the position of gate 130. Referring to FIGS. 6-8, gate 130 is shown in a closed position (FIG. 6), a first open position (FIG. 7), and a second open position (FIG. 8). By opening gate 130 further in direction 132 a flow rate of the seed from first compartment 150 and second compartment 152 is increased.

The generally constant ratio of opening 170 to opening 140 being exposed results in the mixture of the seed being emptied from container 100 maintaining a generally constant ratio regardless of the position of gate 130. In one embodiment, the ratio of seed from second compartment 152 to the seed from first compartment 150 being emptied from container 100 is about 5 to 95. Of course the relative sizes of opening 140 and opening 170 may be adjusted to alter the ratio of the mixture of seed being emptied from container 100.

Returning to FIG. 1, container 100 includes a plurality of spaced apart feet 210. Feet 210 are spaced apart to allow the arms of a forklift to be able to pass between feet 210 and to elevate container 100.

Container 100 may be coupled to a planting device such that seed exiting container 100 is planted in the ground by the planting device. Exemplary planting devices include pull-behind planters, drills, and other suitable planting devices. In one embodiment, since the ratio of the first type of seed exiting a first compartment of the container 100 and a second type of seed exiting the second compartment of the container is generally constant, the ratio of the first type of seed to the second type of seed planted by the planting device is generally constant.

While this invention has been described as relative to exemplary designs, the present invention may be further modified within the spirit and scope of this disclosure. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains.
